WELDSIM Simulations of Alu-Steel Butt Welds Produced Using the Hybrid Metal Extrusion and Bonding (HYB) Process
(Master thesis, 2020)Hybrid metal extrusion and bonding (HYB), er en fast fase sammenføynings prosess. Først utviklet for sveising av aluminium. Men også kapabel til å sveise ulike metaller. Prosessen bruker tilføring av materiale ved hjelp ... -
Welfare against crime: Can the absence of crime among the second generation immigrants in Sweden bring forward new insights to public policy?
(Master thesis, 2014)In both Europe and the United States, researchers have found the second generation immigrants to commit more crime compare to the first, despite the fact that the second generation is expected to be better off. This thesis ... -
Welfare Attitudes: The Challenge of Globalization: A Multilevel Analysis of the effects of Economic Globalization on Welfare Attitudes
(Master thesis, 2013)Public opinion is important for advanced and aspiring democracies because it is the people that are the ultimate source of power in these societies. Peoples’ attitudes towards economic questions are thus important for a ... -
Welfare Competition in Norway
(Working Paper Series, 1503-299X; 2004:7, Research report, 2004)Local redistribution policy creates incentives for welfare migration that may result in 'underprovision' or even a 'race to the bottom'. This paper evaluates the empirical importance of welfare competition. Our contribution ... -
Welfare Effects of Changing Technological Efficency in Regulated Open-Access Fisheries
(Peer reviewed; Journal article, 2022)Small-scale fisheries often operate under conditions of regulated open access; that is, the fishery is subject to natural or regulatory constraints on fishing technology, including regulations of fishing gear and fishing ... -
Welfare State Regimes and Income Related Health Inequalities: A Comparison of 23 European Countries
(Peer reviewed; Journal article, 2008)Objective: The objective of this study was to determine whether the magnitude of income-related health inequalities varies between welfare regimes (Scandinavian, Anglo-Saxon, Bismarckian, Southern and Eastern). Specifically, ... -
Welfare Technologies in Care Work
(Journal article; Peer reviewed, 2019)Welfare technologies have within the last few years become a new mantra for reforming the Nordic public health and social care, and are increasingly making their impact on working life of care professionals. Welfare ... -

Well Control Aspects of Riserless Drilling
(Master thesis, 2013)This master thesis has investigated feasibility of effective well control in riserless drilling. An attempt was undertaken to design a realistic model of riserless well using advanced multiphase simulation tool and evaluate ... -
Well Control Optimization by Coupling Smart Proxy Models with Genetic Algorithm
(Master thesis, 2021)Generally, optimal well controls to maximize net present value (NPV) are obtained by coupling of numerical reservoir simulation with an optimization algorithm. This approach requires a significant number of numerical ... -
Well Control Optimization in Waterflooding Using Genetic Algorithm Coupled with Machine Learning Models
(Master thesis, 2020)Generally, optimum well controls to maximize net present value (NPV) in a waterflooding operation are obtained from a numerical reservoir simulation in combination with an optimization algorithm. This procedure is often ... -
Well control with Controlled Mud Pressure: Reviewing AGR’s well control procedures for the CMP system, analyzing and comparing with conventional well-control procedures, possible impact of technology.
(Master thesis, 2011)Dual Gradient Drilling (DGD) are a portfolio of drilling systems that in various ways pumpreturns from the well through a mud return line (MRL) from the seafloor, or somewhere between the seafloor and the rig floor. Two ... -
Well control with Low Riser Return System
(Master thesis, 2011)A response to the increasingly more challenging prospects to drill, due to depletion of old reservoirs and increasing water depths, is the Low Riser Return System (LRRS). The LRRS is a system designed to manage the wellbore ... -
Well Integrity Assessment: Challenges related to Human and Organizational Factors - The case study of Veslefrikk
(Master thesis, 2015)Well integrity affects safety, humans, the environment, production, reputations and assets value. The concept of well integrity in relation to human and organizational factors have gained considerable attention in the ... -
Well Integrity behind casing during well operation.Alternative sealing materials to cement
(Master thesis, 2013)Maintaining well integrity during all well operations has become a major concern for operators worldwide. The maintenance of an increasingly aging well stock and the higher cost associated with new wells makes well integrity ... -
Well Log and Seismic Data Interpretation: Rock Physics Study of Poorly Consolidated Sandstones in The North Sea
(Master thesis, 2012)We use rock physics models for poorly consolidated rocks to diagnose reservoir sandstones in the Alvheim Field, North Sea. Geological factors that will control the rock physics and seismic properties include clay content, ... -
WELL LOG ZONATION AND CORRECTION BASED ON VARIATIONS IN AMPLITUDE AND LAYER THICKNESS
(Master thesis, 2011)Well log zonation is the usual practice to carry out well log analysis. Definition of bed boundaries at a very detailed level is difficult and time-consuming, and therefore some data is frequently untapped, especially when ... -
Well Models for Production Optimization
(Master thesis, 2008)In coupled reservoir simulations a model of a reservoir and the production system are joined together to obtain realistic responses. One way of performing production optimization is to make use of a gas oil ratio (GOR) ... -
Well Path Optimization on a CO2 EOR Project
(Master thesis, 2019)Optimering er eit heller nytt emne i petroleumsindustrien, men har i det siste sett auka interesse. Innanfor EOR, eller Enhanced Oil Recovery, kan optimeringstilnærmingar bli implementert for meir fordelaktige brønnbanar. ... -
"Well Placement for maximum production in the Norwegian Sea": Case Study: Norne C-segment Oil Field
(Master thesis, 2012)In petroleum fields, the essence of well placement is to develop and maintain petroleum reservoirs in order to achieve maximum production for economic benefit. Maximum production can be achieved with more oil wells, but ...
